I just purchased a BLUE Bluebird microphone for a gig I did over the weekend and was very impressed by this microphone. Any others used the BLUE series and have any thoughts on them? I found this particular microphone to have a very open, very neutral, very pleasing quality. I was using it to record a soprano in a soprano/piano recording session. The piano was recorded with two AT-4051s. I normally record this piano with two AKG Blueline microphones but did not have access to them for this session. Any thoughts on the BLUE series would be most welcome.
